Is SPF in Your Cosmetics Creating a False Sense of Protection?

Considering the astonishing fact that sun damage accounts for almost 80% of premature aging, this is very much preventable. Many of us believe we’re doing all we can to protect our skin, but are we?

Do you know how the sun protection factor (SPF) is calculated, or the difference between SPF 15 and SPF 30? According to Skincancer.org, the SPF number tells you how long the sun’s UV radiation would take to redden your skin when using the product exactly as directed versus the amount of time without any sunscreen. So ideally, with SPF 30 it would take you 30 times longer to burn than if you weren’t wearing sunscreen. Doing the math, SPF 15 blocks about 93% of UV, SPF 30 blocks about 97%, and SPF 50 blocks about 98%. But sunscreens also vary in their ability to protect against UVA and UVB rays.

In a recent article covering The Truth About SPF in Cosmetics, “the beauty industry is overflowing with makeup products containing SPF... up to 50 and even 70 in the US. SPF is featured in skincare, primers, foundations and powders promising to deliver sunscreen protection. Although these makeup products have sunscreen ingredients, they do not have the proper amount of coverage or the capabilities to protect against UVA (aging) and UVB (burning) rays.” And just like you should with sunscreen, are you reapplying your primer or foundation every couple hours? Most likely not, but some protection is better than foregoing it. In many cases it is not stated how often the product should be reapplied. An actual sunscreen may offer better protection, but is just one method of sun protection in the overall strategy to protect your skin.


Why doesn’t Rescue Skin contain an SPF?

Unlike most skincare products that only target the outermost layer of skin, RESCUE Skin’s adult stem cell derived ingredient, MDFc19, penetrates deeper, all the way to the dermis where collagen and elastin are made. Adding an SPF to our formulations would block this and other ingredients from penetrating deep where they naturally support and aid in dermal fibroblast production, which are cells that help your skin recover from injury and produce collagen.
